主题: feedback on composed VPN

I have read the latest version of draft-evenwu-opsawg-yang-composed-vpn-03. I 
believe it aims at decomposing VPN service spanning across domain into VPN 
service in each domain and  provide end to end connectivity service delivery, 
in addition, I believe it can also stitch connectivity service in each domain 
and provide end to end network visibility to the connectivity service. Here are 
a few comments:

1.When a VPN service needs to span different administrative domains, usually 
VPN service in two end or two site in the access are same type VPN service, I 
would suggest to change spaning two AS into three domains or AS, introduce 
L2VPN in two end close to the site

RE: thanks, this is a good scenario, maybe we can add this to figure 2 and 
explain the logic behind it.


2. It is not clear to what config manger1 means? It is domain specific 
controller or NMS or something else, I think it is former, if the answer is 
yes, it will be great to make this clear.

RE: this is a domain specific controller see the text after figure 1 but we can 
make it clearer

Besides this, I think this draft is in good shape and ready for adoption.
